_*Question:*_
How can I modify the cells worker loop (on dof1) initialisation to have a
second iterator linked with a second dof_handler looping at the same time ? or
how can I add a concurrentely running for loop to the cell_worker with a
different iterator ?
I checked in step 16 and 47 as well as in the doc for MeshWorkers and I did
not find a solution to this problem. I hope the question is clear enough, do
not hesitate to inquires more details if I am missing something important.
Sylvain,
it's not going to be possible to hack this into MeshWorker::mesh_loop() in an
easy way. But what you can do is this: Inside your assembler, whenever you are
given a cell iterator pointing to a cell in dof_handler_1, you need to find
the corresponding iterator for dof_handler_2. You can do this in the following
way (up to typos and misspelled function names):
DoFHandler::active_cell_iterator cell_2 (cell_1->get_triangulation(),
cell_1->level(),
cell_1->index(),
cell_1->get_dof_handler());
Best
W.
